MDX frontmatter layout variable forbidden to use ?

[burnt hill]

Hi !

Sorry, might be wrong and it's mostly tied with MDX, but I can't define layout in MDX frontmatter and switch Astro layout, base on that variable. Is it something specific with MDX package or it's Astro hidden rock ?

Thank you !

Example :

---
title: First blog post
authors:
- TommyJ
description: "Hello"
type: "post"
layout: "blog"
---

It will work only with :

---
title: First blog post
authors:
- TommyJ
description: "Hello"
type: "post"
---

So, adding layout: "blog" to MDX will lead to error 👺

layout is a “special” property, so it should be a path to a template file, see https://docs.astro.build/en/basics/layouts/#markdown-layouts

If you just want to have a string for different layouts you then switch between, you’d need to use a different name, e.g. template or whatever.
